Justin Bieber Goes Swimming in His Underwear

Is Justin Bieber turning into an exhibitionist? The pop star was recently captured on camera taking a dip wearing nothing but his underwear.

The singer had previously posted a pic of his abs/crotch on his Instagram account, leaving many fans wondering what exactly he was trying to show off. His underwear were also displayed in that photo, although his bright blue briefs were covered up by a pair of blue jean shorts.

Justin seems to have gotten bolder about showing off his bod in the latest photos that have hit the web. The pop star was photographed by a pool in Miami over the weekend wearing nothing but a light grey pair of underwear. He was joined by his pal Sean Kingston, who stayed a little more covered up with his swimming trunks.

So why in the world was Justin Bieber swimming in his underwear? It's possible that he forgot to pack a pair of swimming trunks, but surely he had some kind of shorts he could have gone swimming in. If he did have such an option available, then maybe Justin Bieber is just getting in touch with his rebellious and spontaneous bad boy side.

After all, the singer is taking a few weeks off to relax and grow up, and he might think that showing off his bod in nothing but his underwear is a way to prove to people that he's not a child star anymore. He's done his best to show everyone that he's a big kid now by dating slightly older star Selena Gomez, whom he has been on plenty of overnight trips with, and by collaborating with older musicians like Chris Brown. So perhaps posing in his underwear is just his latest ploy to show that he's no longer a little boy. Or maybe he just wants to land a job modeling Calvin Klein underwear like Marky Mark.

But if the Biebs is simply embracing exhibitionism, hopefully he doesn't go too far -- he really doesn't need to become the male version of Vanessa Hudgens when he turns 18 next year.
